Subject: bgpd/evpn: Compute {im,ex}port RT from EVPN VRF
X-Git-Tag: 7.1_pulled~111^2~7
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=f9b8094e3b2e608cc926e94eea443b406b60791b;p=matthieu%2Ffrr.git

bgpd/evpn: Compute {im,ex}port RT from EVPN VRF

For default RT, this uses the correct ASN to derive the RT (ASN of the
EVPN VRF).

It also stores them in the EVPN VRF's hash tables rather than in the
default's one.
